What happens to your body when you use ice? by Nicola Garrett. Ice has been called the most dangerous and destructive drug of our time. But what exactly does it do to your body?
Definition. An inverse agonist is a molecule that binds to the same site as an agonist and is considered to be a full agonist. However, it elicits the opposite effect to that of a normal agonist, i.e.: demonstrates negative efficacy.n antagonist reduces the effect of an agonist by preventing it from binding to receptors. Both antagonists and inverse agonists reduce the activity if a receptor and, in the presence of an agonist, reduce its activity.
A receptor antagonist is a type of receptor ligand or drug that blocks or dampens a biological response by binding to and blocking a receptor rather than activating it like an agonist. They are sometimes called blockers; examples include alpha blockers, beta blockers, and calcium channel blockers. In pharmacology, antagonists have affinity but no efficacy for their cognate receptors, and binding will disrupt the interaction and inhibit the function of an agonist or inverse agonist at receptors.
